  • HDD from Mid-2009 MacBook Pro works OUTSIDE laptop, but not INSIDE.

    - by Jaime
    Leading up to the problem: I was working late one night on a Keynote presentation. My battery ran out, and the computer did that hibernation thing it does when there's no battery power. I got my charger, connected it to my computer, and then pushed the power button. It started up for a second in to the gray screen it usually goes to. Then I turned around, tugging the magsafe charger out of the connector on the computer. This caused my computer to shut down again. Now I can't get it to boot at all -- just a blinking folder icon with a question mark in it on boot up. I've tried pretty much everything to deal with this. Multiple forced reboots, resetting PRAM and NVRAM, etc. I booted to original OSX disc and ran disc utility, but I discovered that there is no disc to boot to. I ran the Apple Hardware Test, and it came back 100% good. I booted to an Ubuntu live-boot disc and ran that disc utility, just to see if it recognized a disc at all. It didn't. So I removed the HDD, and replaced it with a bootable volume running BSD. It didn't recognize that HDD either. I then attached my HDD to my computer via an external enclosure with a USB interface. Lo and behold, it booted! So my computer now only work with my HDD attached externally. This means that the HDD is functional. And the AHT returns no hardware malfunctions. So what the hell is going on? … In the meantime: I've put the HDD back into the computer but it still doesn't do anything at all (I'm running it externally right now). I just checked the serial number and my 1 year warranty expired recently, so I can't send it back for repair. … Little Help Thoughts? I've been searching everywhere for leads, but no luck. …

  • apcupsd on Linux does not report on APC BackUPS Pro 900

    - by lserni
    From what documentation I could find, the UPS should be (is!) supported by Linux and ought to work with apcupsd. I looked for specific problems such as the infamous Microlink protocol, and found none. I have found a feedback from a guy in UK that reports using this very model on a not-too-different OS version (his OpenSuSE 12.1, mine 12.3 x86_64). The USB port is detected, lsusb reports Bus 002 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply and lsusb -v -s002:003 confirms and expands: Bus 002 Device 003: ID 051d:0002 American Power Conversion Uninterruptible Power Supply Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 (Defined at Interface level) bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x051d American Power Conversion idProduct 0x0002 Uninterruptible Power Supply bcdDevice 0.90 iManufacturer 1 American Power Conversion iProduct 2 Back-UPS RS 900G FW:879.L4 .I USB FW:L4 bNumConfigurations 1 Configuration Descriptor: [...] Interface Descriptor: [...] bInterfaceClass 3 Human Interface Device bInterfaceSubClass 0 No Subclass bInterfaceProtocol 0 None iInterface 0 HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 1.00 bCountryCode 33 US bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 1134 Report Descriptors: ** UNAVAILABLE ** Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 3 Transfer Type Interrupt Synch Type None Usage Type Data wMaxPacketSize 0x0008 1x 8 bytes bInterval 100 Device Status: 0x0000 (Bus Powered) The kernel recognizes this and duly sets up crw------- 1 root root 180, 96 Nov 4 16:11 /dev/usb/hiddev0 As far as I know, everything is as it should be. I have put the standard configuration in /etc/apcupsd/apcupsd.conf (which is Unix-terminated, ASCII-only, no BOM (just in case)) UPSCABLE usb UPSTYPE usb DEVICE (I have also tried commenting out DEVICE, and setting a device of /dev/puppa results in an access attempt to /dev/puppa, not some /var/lib/dev/puppa or /dev/puppa\r\n). Yet, what apcaccess tells me is VERSION : 3.14.10 (13 September 2011) suse CABLE : USB Cable DRIVER : USB UPS Driver UPSMODE : Stand Alone STARTTIME: 2013-11-04 16:24:22 +0100 MODEL : STATUS : NOBATT LINEV : 000.0 Volts LOADPCT : 0.0 Percent Load Capacity BCHARGE : 000.0 Percent TIMELEFT : 0.0 Minutes MBATTCHG : 5 Percent MINTIMEL : 3 Minutes MAXTIME : 0 Seconds SENSE : Low LOTRANS : 000.0 Volts HITRANS : 000.0 Volts It doesn't recognize the model, and reports no battery (and no voltage). This confirms that it's not the Microlink problem, or it would report the battery status, if precious little else. If I disconnect the USB cable, I get an apcupsd message to the effect that communications have been lost; and I get the "communication restored" broadcast too, if I reconnect the cable. apcupsd is monitoring. So everything tells me that it should work -- only it doesn't. Does anyone spot what I'm missing?

  • Windows 7: System date and time resets to 2007

    - by Rogue
    My desktop computer has been upgraded to Windows 7 and ever since whenever I start it up, it resets the date and time to 2007. I tried changing the battery on the motherboard thinking that it would solve, but its still the same. I didn't face this trouble when Windows XP was installed on this computer. Any ideas how to fix this?

  • Power scheme faulty

    - by user40287
    Hi, I use a laptop. When I take the power cable out to run on batteries, the screen darkens, as it is no longer so bright, to save on battery power. When I put the power cable back in, the screen brightens back to it's original brightness. However, I have since replaced the power cable, and the screen remains darkened. How do I regain the original brightness? Thanks, Steve

  • iPhone log reader

    - by Alexis Hirst
    I went to the apple store today to discuss a problem with my iPhone battery, and they plugged it into one of their macs and used an application that interpreted the logs stored on my phone. So, my question is, does anybody know the name of the application that reads the logs, and if so, where it is available? Since it is a diagnostic tool, I'm guessing it won't be openly available, but I thought i would ask anyway.

  • I want to plot ocean current with a GPS in a bottle.

    - by Fantomas
    Thinking of using a wine bottle with a cork that barely sticks out. Anyhow, I want to put in a GPS, a battery and a transmitter and to be able to collect position about every minute or so. Off-the-shelf components are preferred. What are my options as far as hardware and software choices? Thank you in advance!

  • How to stop switchable graphics from switching to high-power GPU when charging the laptop?

    - by Saifallah
    I've an Acer laptop with Windows 7 64 bit and an ATI Radeon HD 6550M Graphics card. Whenever I connect the power to charge the battery it automatically switches to the high-power GPU (ATI) instead of the low-power (Intel) GPU. There's an option in the bios to stop such thing but it makes the GPU runs always on high-power and I can't switch to the low-power GPU. How can I prevent the switchable graphics from automatically using the high-power GPU when charging?

  • Is "Turn Off Windows write-cache buffer flushing" safe on a laptop?

    - by Earlz
    my laptop's internal harddrive is a bit slow. I looked at the drive properties and there are two options: [X] Enable write caching on the device [ ] Turn off windows write-cache buffer flushing on the device As you can see, the first option is checked already, but the second option isn't. I've heard the second option can really speed things up, but it also sounds very risky. Is it safe to do on a laptop that rarely is off of AC power? (but still has battery as well)

  • Self-Charging, USB Portable Speaker Recommendations

    - by Koobz
    There are lots of strictly usb powered speakers, but I don't imagine they're that good. I'd like something that I can plug in at home, have the speakers charge and when I go to the park with my friends, I'm not compromising sound quality or battery life. Does anything like this exist?

  • Does more heat generation mean more wear and tear?

    - by Suhail Gupta
    I read that hardware generally used on PC is not optimized for running Linux. That is the reason the machine emits large amount of heat and doesn't give the battery back up , that we will get while working on windows. ~REF Does it also mean more wear and tear of the hardware (when using linux as compared when using windows ) ? Note : I have personally experienced large heat emission while working with Fedora 16 and Ubuntu 11.xx on my laptop.

  • What happens in case of utility power failure?

    - by Jake
    (in the office) Today, the UPS battery replace warning light lit up and there was a slight panic as the all the technical people will not be around the next few days. But after thinking a bit further, I realise that in case of power failure, no client computers will be able to turn on in the first place and operations will be disrupted regardless of whether the UPS keeps the server up. This makes me wonder if the UPS is really such a critical component? What do you think?

  • Holding off Windows 2000/3 Server in Shutdown

    - by user1668993
    We have a C# VS2010 application running on a Windows 2000 Server box (there is also a Windows 2003 Server box) as pretty much the only application running. We remove power from the box. There is a short duration battery (maybe 3 minutes of power) which then waits 10 seconds and then decides things are coming down and notifies Windows that it needs to shut down. Windows sends a CTRL_SHUTDOWN_EVENT event to the application which fields it and tries to keep Windows from going down for a while to let another computer which communicates with this one time to do some file work on the first computer. It does this by a timing loop and after the loop is over, it exits gracefully and the computer shuts down. Nice plan but it doesn't work. The application gets to maybe 20 seconds and the application is forcibly killed by Windows and Windows shuts down. At 90 seconds, the hardware firmware running the battery turns off power to the computer. I have tried searching to find out how to hold off Windows for a bit of time. I tried creating (it wasn't there) the HKEY_LOCAL_MACHINE subtree: \SYSTEM\CurrentControlSet\Control\WaitToKillAppTimeout registry key to 60000 but though it seemed to keep the popup from happening, Windows itself died at about the same amount of time -- we think without having the opportunity to shut itself down gracefully. Maybe the registry key worked but wasn't enough. Basically I have an "ill-mannered" application which is refusing to shut down (for the best of reasons) and without the registry key thing, Windows eventually shuts it down anyway and then shuts itself down. With the registry change, we think what is happening is that Windows doesn't shut down the application but Windows itself is killed suddenly without shutting down but power is still not pulled for about another minute, and then power is pulled. So maybe we have layers here. First there is how long the application tries to stay open. Then there is how long Windows is prepared to allow it to stay open. Then there is ... something... which kills windows. Then there is the power loss. Anyone have any ideas how we can get windows to stay open and in operation say to 70 seconds instead of about 20? Is our registry key right, but not enough? Is there some additional key we need to set to determine how long after windows is notified of a shutdown before it just kills itself? Thanks in advance.

  • Safely reboot prior to recovering data

    - by ELO
    What is the safest (without additional writing to the disk) way to power down computer whose deleted files you want to recover in order to boot from rescue medium? In case of a desktop computer, plugging off the power cord looks like the most direct solution, but are there possible side-effects, apart from losing unsaved data? More problematic seems the laptop, with removing the battery being the equivalent, but is it a good idea overall?
